Question

John wanted to investigate Newton's second law to see how changing the force applied to an object affects the object's motion. He used eight different values of force applied to the same object, which had a mass of 1 kg. This resulted in eight different values for acceleration. John's results are shown in the graph below, which plots force vs. acceleration for the 1-kg object. Examine the graph, and then answer the question that follows. Based on the graph above, it can be concluded that

A. the acceleration of an object decreases as the force applied to the object increases.

B. the acceleration of an object remains the same as the force applied to the object increases.

C. the acceleration of an object increases and decreases randomly as the force applied to the object increases.

D. the acceleration of an object increases as the force applied to the object increases.

Answer 1

10 m/s2

Step-by-step explanation:

Based on the graph, it can be inferred that applying a force of 10 N to the object will cause the object to accelerate 10 m/s2. This inference can be made by following the trend of the plotted data. By extending the straight data line farther toward the upper right, it can be seen that the acceleration value of 10 m/s2 matches the force value of 10 N.

The relationship between force and acceleration shown in the graph can be summarized by Newton's second law, which is shown below.

Force = Mass × Acceleration

Answer 2

This is not a physics problem. This is a math problem ... reading
a graph ... and I'm really kind of disappointed that you couldn't
answer it on your own.

Please.
Look at the graph again before I dump the answer at your feet.

-- When the force is zero, the acceleration is zero.
-- When the force is 2 newtons, the acceleration is 2 m/s² .
-- When the force is 4 newtons, the acceleration is 4 m/s² .
-- When the force is 6 newtons, the acceleration is 6 m/s² .
-- When the force is 8 newtons, the acceleration is 8 m/s² .

Now, the answer:

-- As you increase the force applied to an object,
the object's acceleration increases.
